Having a few little annoying faults with my 2007 GV at the moment....grrrrr
One problem I've noticed, after switching the engine off, I can hear a hising noise for about 15-20 seconds, then it stops.
I've reasoned that it's some kind of vacuum leak, because pressing on the brake pedal (ie operating the servo) when the engine's switched off causes the hissing to stop sooner. It's coming from the area to the right of the dipstick tube, there's a load of tubing/valves in that area, nothing obvious is damaged.
It's definitely a vacuum leak, because I've also noticed that after the hissing has stopped, the brake pedal is solid, just like the servo is exhausted.
It's probably leaking when the engine is running but I can't hear it due to the background noise.
Any ideas ???
cheers
After further reading on the forum, I think this could well be related to the EGR valve ???
